Further Implementing A*

Following on from my earlier post; A* Pathfinding, I have now started to implement the A* pathfinding I have learnt into the core of the game, but have reached small snags up to this point.

I have now got a visible grid being instantiated along with the node points, with both node and tile having each other as variables. I have been able to tweak and apply GameManager.cs into the A* build. Units are spawning, and can be moved around the map, as they could with the original pathfinding.

The mouse can now operate as the target position; Once the player starts to move a unit, the target transform will go to any tile moused over, with the path being painted in the scene editor via the use of gizmo's.

One issue so far, is the order of movement. At this time, when a unit goes to move, rather than going from seeker position to target, the unit appears at the target, and moves back to its original position. Rather than following along the path square-by-square, the unit continues to shoot immediately to the destined position. This is one major aspect I believe must be locked down, as it is the biggest impediment at the current time.

As a more minor issue, I am struggling to have the tiles change colour to create a visible path line to the player in the game, rather than just the scene manager.

My next steps will be:

• Ensure a unit is travelling to the end target
• The unit moves square by square, instead of travelling as the crow flies
• Basic visual movement feedback for the player
